Tujuh Village is geographically intersected with Citarum watersheds and according to the Regional Government of West Java Province (2019); this village is one of the areas prioritized by the government to become a land and water conservation area in the national program of "Citarum Harum". Tujuh Village has the characteristics of an uneven and hilly region with relatively dry mineral soil and limited water availability that will experience drought in a number of places during dry season. The objectives of this community service program are (1) providing knowledge to farmers regarding soil and water conservation techniques using Organopore Infiltration Hole and (2) controlling organic waste from agricultural activities. One of the solutions to overcome the environmental and biophysical problems that occur in Tujuh Village is by making an Organopore Infiltration Hole. The principle of this organopore hole is almost the same as the Biopore Infiltration Hole, which is making a vertical hole with a diameter of 10 cm and a depth of 0-100 cm. The difference is that this organopore hole uses a basket made of wire to collect organic waste that will be made into natural compost within the hole that can improve soil ecological stability. The research was implemented by adopting the Participatory Rural Appraisal (PRA) approach, which allows sub-district communities to share, improve and analyze their knowledge regarding village conditions and life, as well as plan and perform concrete actions.

Indonesia sebagai salah satu negara berkembang juga diwajibkan untuk mengurangi sumber emisi gas seperti CO2, emisi pabrik, transportasi dan penggunaan energi fosil pada pembangunannya. Salah satu usaha yang dilakukan dalam menghadapi meningkatnya gas rumah kaca adalah meningkatkan kemampuan vegetasi baik hutan, kebun dan tanaman lain dalam mengikat CO2. Karbon yang tersimpan pada hutan tanaman baik yang terdapat pada bagian atas dan bagian bawah merupakan suatu cadangan sumber daya alam yang dapat digunakan bagi keberlangsungan hidup terutama dalam kondisi krisis lingkungan global yang terjadi saat ini. Penelitian ini didasarkan pada pendugaan cadangan karbon pada biomassa, nekromassa Acacia crassicarpa dan tanah gambut hutan tanaman industri di Kabupaten Bengkalis Provinsi Riau. Tujuan penelitian ini adalah untuk menghitung cadangan karbon (carbon stock) pada biomassa, nekromassa Acacia crassicarpa dan tanah gambut hutan tanaman industri di Kabupaten Bengkalis Provinsi Riau dan mengestimasi pembangunan hutan tanaman industri yang berkelanjutan pada lahan gambut di Kabupaten Bengkalis Provinsi Riau. Metode yang digunakan pada penelitian ini melalui pendekatan metode dominant quantitative-less dominant qualitative dan metode pengumpulan data pada penelitian ini didominasi menggunakan metode survai. Hasil penelitian menunjukan bahwa besarnya cadangan karbon pada biomassa 2.808.363,28 t c/ha, nekromassa 2004, 437 t c/ha dan tanah gambut sebesar 560.938,5 t c/ha. Keberadaan hutan tanaman industri dapat memberikan jasa ekologis berupa cadangan karbon apabila dilakukan pengelolaan yang tepat, khususnya memiliki peluang simpanan pada nekromassa dan tanah gambut.

AbstrakProduktivitas kelapa sawit tidak terlepas dari peran serangga penyerbuk Elaeidobius kamerunicus Faust. Berbagai kondisi lingkungan yang kurang mendukung dan musuh alami dapat menurunkan populasinya. Tujuan penelitian ini untuk mempelajari pengaruh cuaca, musuh alami dan persentase kerusakan buah terhadap populasi serangga penyerbuk E. kamerunicus di tanah sulfat masam. Penelitian dilakukan menggunakan metode observasi di lapang produksi di Selangkun Estate, Rungun Estate, PT. Sawit Sumbermas Sarana Tbk. dan Kanamit Estate, PT. Menteng Kencana Mas, Kalimantan Tengah, Indonesia pada tanaman berumur 6 dan 9 tahun sebanyak 4.144 tanaman atau seluas 30 ha.. Analisis data pada penelitian ini menggunakan ANOVA dan Uji lanjut Tukey untuk melihat preferensi E. kamerunicus pada bunga betina di tanah sulfat masam, dan korelasi Pearson untuk melihat pengaruh musuh alami dan kerusakan buah terhadap populasi E. kamerunicus. Hasil penelitian menunjukkan bahwa kunjungan E. kamerunicus tertinggi pada tanah sulfat masam terjadi pada pukul 11.00 WIB sebanyak 116,33 kumbang yang berbeda nyata dibandingkan pada waktu pengamatan lainnya. Kunjungan E. kamerunicus ke bunga betina mekar banyak terjadi pada kisaran suhu 31 – 32 0C dengan kelembapan relatif antara 68 – 75%. Laba-laba (Gasterachanta diardi dan Argiope sp.) merupakan salah satu musuh alami kumbang E. kamerunicus. Jumlah jaring laba-laba yang terdapat pada satu tanaman menunjukkan korelasi positif secara nyata terhadap jumlah E. kamerunicus yang terperangkap dengan nilai Pearson Correlation sebesar 80,4% dan R Square sebesar 64,69%. Tanaman yang memiliki bunga jantan terserang tikus dapat menurunkan populasi E. kamerunicus meskipun tidak berbeda nyata. Persentase kerusakan buah tidak berkorelasi nyata dengan populasi E. kamerunicus per ha pada 0, 1, 2, dan 3 bulan setelah pengamatan.Kata Kunci : Elaeidobius kamerunicus ∙ Kelapa sawit ∙ Musuh alami Abstract Oil palm productivity is inseparable from the role of pollinator insect namely Elaeidobius kamerunicus Faust. Various unfavorable environmental conditions and natural enemies can reduce the population of such insect. The purpose of this study was to find the effect of climate, natural enemies and fruit damage percentage on the insect population of E. kamerunicus in acid sulfate soil. The research was conducted using the observation method in the production field at Selangkun Estate, Rungun Estate, PT. Sawit Sumbermas Sarana Tbk. and Kanamit Estate, PT. Menteng Kencana Mas, Central Kalimantan, Indonesia on 4,144 plants aged 6 and 9 years on the area of 30 ha. The data analysis in this study used ANOVA and Tukey's further test to see the preference of E. kamerunicus on female flowers in acid sulfate soils, and Pearson correlation to see the effect of natural enemies and fruit damage on the population of E. kamerunicus. The results showed that the highest visitation of E. kamerunicus on acid sulfate soils occurred at 11.00 WIB as many as 116.33 beetles which were significantly different from other observations. The visits of E. kamerunicus to blooming female flowers occurred in the temperature range of 31 – 32 0C with relative humidity between 68 – 75%. The spider (Gasterachanta diardi and Argiope sp.) is one of the natural enemies of the E. kamerunicus beetle. The number of spider webs found in oil palm tree shows a significantly positive correlation to the number of trapped E. kamerunicuswith a Pearson Correlation value of 80.4% and R Square of 64.69%. Plants with male flowers attacked by rats experienced the reduction of the population of E. kamerunicus, although it was not significantly different. The percentage of fruit damage was not significantly correlated with the population of E. kamerunicus per ha at 0, 1, 2, and 3 months after observation.Keywords : Elaeidobius kamerunicus ∙ Palm oil ∙ Natural enemies

Dalam mendukung penerapan program pemerintah mewujudkan pertanian berkelanjutan (sustainable farming), salah satu upaya yang dapat ditempuh yaitu dengan memanfaatkan kembali limbah hasil kegiatan pertanian. Limbah hasil kegiatan pertanian tersebut diolah dengan menggunakan teknologi yang sederhana hingga menggunakan teknologi modern sehingga akan menghasilkan suatu produk yang bernilai. Desa Tugumukti merupakan desa yang berada di Kecamatan Cisarua, Kabupaten Bandung Jawa Barat yang memiliki wilayah geografis berbukit dan memiliki perkebunan teh yang cukup luas. Banyaknya hasil kegiatan pertanian dari perkebunan teh yang berada di sekitar desa, khususnya sisa hasil pertanian berupa ampas teh, menjadi hal menarik yang perlu disosialisasikan dalam pemanfaatan teh tersebut. Pengabdian masyarakat ini dilakukan dengan metode penyuluhan. Metode ini digunakan sebagai bentuk sosialisasi yang memungkinkan sesuai dengan kondisi desa dalam memberikan informasi dan berdiskusi bersama masyarakat dalam mengetahui dan memahami apa itu ampas teh serta menjelaskan teknologi ramah lingkungan yang dapat digunakan dalam pemanfaatan ampas teh. Ampas teh yang merupakan limbah atau zat sisa dapat memberikan manfaat dan nilai tambah dengan melakukan daur ulang limbah teh. Ragam teknologi ramah lingkungan telah banyak dikembangkan saat ini dalam pemanfaatan ampas teh, diantaranya penerapan produksi bersih, pemanfaatan ampas teh sebagai adsorben dan pemanfaatan ampas teh sebagai media tanam jamur tiram putih. Ragam teknologi ramah lingkungan ini diharapkan dapat memberikan kontribusi sebagai salah satu wujud dari penerapan pertanian berkelanjutan (sustainable farming).

Microgreen, especially because there is currently a Covid-19 pandemic that has hit almost all countries. Microgreen cultivation techniques are different from other urban farming and are easier to apply so that people are interested in cultivating them. The results showed that 109 respondents who live in urban areas and are familiar with microgreens, 98.2% have an interest in developing microgreens and the remaining 1.8% are not. The reason respondents are interested in microgreen is because it is easy to apply so as to produce quality vegetables that are good for health and microgreens are believed by the respondents to open up new business opportunities. The price offered on this microgreen is much higher than the price of conventional vegetables in general. This can be a potential business with the middle to upper market segment because microgreens are used as food ingredients such as salads or decorations in food in middle to upper class restaurants. In addition, microgreens can also go to supermarkets where the target consumers are consumers who will be aware and ready to be marketed at premium prices.

ABSTRACT The 3R Waste Management Center is located in the Pondok Pekayon Indah housing complex RW 011 Pekayon Jaya sub district, South Bekasi sub district, which is protected by the Environmental Care Movement Foundation, a foundation that has been composting organic waste since 2003. Composting is a process in which organic matter is decomposed biologically, especially by microbes that use organic matter as an energy source. Making compost is to regulate and control this natural process so that compost can form more quickly. The stages of composting carried out by the Environmental Care Movement Foundation include; Garbage collection, waste sorting or sorting, First Enumeration, Transfer and Addition of EM-4 Activator, Fermentation Stage, Second Enumeration, Screening or Screening, Packaging and Storage. The compost produced by the Environmental Care Movement Foundation has been tested by the Laboratory of the Department of Soil Science and Land Resources, Faculty of Agriculture, IPB since 2015 issued by the Sanitation Service of the Bekasi City Government. This is an added value for compost made by the Environmental Care Movement Foundation, because the results of laboratory tests can convince people who will use or even buy compost made by the Environmental Care Movement Foundation. Thus, the compost fertilizer business opportunity for the community (sociopreneurship) is very wide open because the quality of the compost is guaranteed.
